Description

The present invention relates to a light emitting unit having a plurality of semiconductor light emitting elements and a lighting device including a light emitting unit.

Conventionally, a lighting device in which a luminous body such as an incandescent lamp or a fluorescent lamp is attached to an instrument main body and the instrument main body is attached to an attachment target surface such as a ceiling or a wall is widely used. In addition to the light emitter, a power supply circuit, a lighting control circuit, a wireless antenna, and the like are also arranged inside the lighting device. Since the conventional lighting device has a certain amount of space, a power supply circuit, a lighting control circuit, a wireless antenna, and the like can be freely installed inside the lighting device.

In recent years, it has been proposed to use a light emitting diode (LED: Light Emitting Diode) as a light emitting element, which consumes less power than conventionally used incandescent lamps and fluorescent lamps and has excellent durability. .. Since LEDs are thinner than incandescent lamps and fluorescent lamps, the lighting device can be made thinner.

Japanese Unexamined Patent Publication No. 2013-179014

However, when the lighting device is made thinner, the spare space is narrowed, so that the power supply unit (for example, having a board on which the power supply circuit and the lighting control circuit are mounted), the wireless antenna, the wireless control circuit, etc. can be freely arranged. It gets harder. In particular, there is a concern that noise generated in the power supply unit is transmitted to the wireless antenna and the wireless control circuit to reduce the antenna reception sensitivity. In addition, we want to arrange the wireless antenna and wireless control circuit so that they do not block the light emission of the light emitting element.

In view of the above circumstances, it is an object of the present invention to provide a light emitting unit capable of reducing the influence of noise generated from a power supply unit on a wireless antenna and a wireless control circuit and not deteriorating the light emitting characteristics of the light emitting element. Another object of the present invention is to provide a lighting device including this light emitting unit.

In order to solve the above problems, the light emitting unit of the present invention

As shown in FIGS. 6 (A) and 6 (B), the appliance main body 10 includes a mounting member 11, side plates 12 (12a and 12b), spring portions 13 (13a and 13b), a terminal block 14, and the terminal block 14. To be equipped. The mounting member 11 is formed with a suspension bolt hole 15 and a power supply cable hole 16.

Hereinafter, each part of the instrument main body 10 will be described in detail.
The mounting member 11 includes a bottom plate portion 114 corresponding to the bottom surface of the light emitting unit mounting recess 111, and a side edge portion 112 formed with the bottom plate portion 114 interposed therebetween and extending in one direction. The bottom plate portion 114 and the side edge portion 112 form a recess in the longitudinal cross section of the mounting member 11.

The mounting member 11 is formed by using, for example, a metal plate. That is, by bending the metal plate, a light emitting unit mounting recess provided with an opening so that the transparent cover 22 of the light emitting unit 20 including the light emitting element 21 and the transparent cover 22 covering the light emitting element 21 can be inserted. Most of 111 is formed. In addition to the metal plate, the mounting member may be formed by injection molding or press molding using, for example, a resin material. The light emitting unit mounting recess 111 extends toward the opening edge of the light emitting unit mounting recess 111.

The side edge portion 112 includes, for example, the first side edge portion 112a and the second side edge portion 112b shown in FIG. 6 (B). The side edge portion 112 has a protruding shape that protrudes toward the light emitting unit 20. It is sufficient that at least one of the first side edge portion 112a and the second side edge portion 112b has a protruding shape protruding toward the light emitting unit 20 (that is, toward the −Z direction in FIG. 6).
The protruding shape here is, for example, an "L" shape that extends outward from each end of the bottom plate portion 114 in the lateral direction and then is folded outward. The portion extending from each end of the bottom plate portion 114 corresponds to the above-mentioned inner wall, and the folded portion forming the "L" shape is referred to as a folded portion.

The bottom plate portion 114 faces the mounting surface of a building material such as a ceiling or a wall, and a hole 15 for a hanging bolt for mounting the lighting device 1 on the mounting surface and a power supply cable are provided in the lighting device 1. It is provided with a hole 16 for a power supply cable for drawing in.

The side plate 12 is attached so as to cover both ends of the attachment member 11 in the longitudinal direction. As shown in FIG. 6B, the first side plate 12a is mounted so as to cover one end of the mounting member 11. The second side plate 12b is attached so as to cover the other end of the attachment member 11. By attaching the first and second side plates 12a and 12b to the mounting member 11, a light emitting unit mounting recess 111 and an opening are formed.
That is, the "light emitting unit mounting recess 111" indicates a space surrounded by the bottom plate portion 114, the first side edge portion 112a and the second side edge portion 112b, and the first side plate 12a and the second side plate 12b.

Further, the "opening" is a folded portion (top portion) of the first side edge portion 112a and the second side edge portion 112b, and an end edge portion of the first side plate 12a and the second side plate 12b opposite to the mounted surface. Indicates the enclosed area.

As shown in FIGS. 7A and 7B, the instrument body 10 may include a position regulating member 113 that regulates the mounting position of the light emitting unit 20. The position regulating member 113 may be arranged in the light emitting unit mounting recess 111.
The position regulating member 113 comes into contact with the light emitting unit 20 when the light emitting unit 20 is attached to the instrument main body 10. As a result, the light emitting unit 20 is positioned at a predetermined position in the light emitting unit mounting recess 111.

For example, as shown in FIG. 7A, the position regulating member 113 may be provided so as to project from the inner wall constituting the light emitting unit mounting recess 111 into the light emitting unit mounting recess 111. At this time, the position regulating member 113 is made of a metal material or the like fixed to the inner wall constituting the light emitting unit mounting recess 111, and is formed of a member different from the light emitting unit mounting recess 111.

Further, the position regulating member 113 may be formed by bending the metal plate of the mounting member 11 so as to be integrally formed with the side edge portion 112. Specifically, a notch is formed in a part of the inner wall constituting the light emitting unit mounting recess 111, and the metal plate is bent so that the notch protrudes into the light emitting unit mounting recess 111, for example, in a U-shaped cross section. Alternatively, the position regulating member 113, which is a protruding portion having a U-shaped cross section, can be formed.

Further, the position regulating member 113 may be arranged as a separate member on the side plate 12 constituting the light emitting unit mounting recess 111. Alternatively, for example, as shown in FIG. 7B, the position regulating member 113 may be formed integrally with the side plate 12.
At this time, the position regulating member 113 is provided so as to project from the side plate 12. Specifically, in the facing region (the region shown by the dotted line in FIG. 7B) facing the light emitting unit 20 when the light emitting unit 20 is attached to the instrument main body 10, a part of the side plate 12 is formed in the light emitting unit mounting recess 111. The position regulating member 113 is formed by bending toward.

As shown in FIG. 6B, the spring portion 13 is fixed to, for example, the bottom plate portion 114 of the mounting member 11. The spring portion 13 is used to maintain a state in which the light emitting unit 20 is inserted into the light emitting unit mounting recess 111 of the instrument main body 10 by engaging with the spring receiving portion 27 of the light emitting unit 20 described later.
Specifically, the first spring portion 13a engages with the first spring receiving portion 27a of the light emitting unit 20, and the second spring portion 13b engages with the second spring receiving portion 27b of the light emitting unit 20. That is, the first spring receiving portion 27a and the second spring receiving portion 27b, and the first spring portion 13a and the second spring portion 13b are in an attached state in which the light emitting unit 20 is attached to the instrument main body 10 (attaching member 11). Functions as a maintenance unit.
The spring portion 13 may be provided in the light emitting unit 20, and the spring receiving portion 27 may be fixed to the bottom plate portion 114 of the mounting member 11.

Specifically, the power supply cable 40 derived from the mounted surface such as the ceiling or the wall is electrically connected to the power supply unit 28 described later via the terminal block 14. The terminal block 14 is attached to the attachment member 11 by, for example, a screw or the like.

The suspension bolt hole 15 is inserted through the suspension bolt 30 in order to attach the appliance main body 10 to the mounting surface such as a ceiling or a wall by the suspension bolt 30 shown in FIGS. 4 (A) and 4 (B). It is a provided hole.

The power supply cable hole 16 is a hole provided for drawing the power supply cable 40 led out from the mounting surface such as the ceiling or the wall into the light emitting unit mounting recess 111 of the instrument main body 10.

[Light emitting unit]
Hereinafter, the configuration of the light emitting unit 20 will be described.
FIG. 8 is a perspective view showing the appearance of the light emitting unit 20 from above.
FIG. 9 is a cross-sectional view of the lighting device 1 including the light emitting unit 20.
FIG. 10 is a plan view illustrating a light emitting element substrate 23 included in the light emitting unit 20.
FIG. 11 is a perspective sectional view taken along the line AA'shown in FIG.
FIG. 12 is an enlarged perspective view showing a part of the light emitting element support member 24 shown in FIGS. 4 (A) and 4 (B) on the substrate support region 24a side.
FIG. 13 is an exploded perspective view illustrating the configuration of the power supply unit 28 of the light emitting unit 20. Other parts of the light emitting unit 20 are also shown for ease of understanding.
FIG. 14 is a cross-sectional perspective view illustrating the configuration of the reflection member 29 of the light emitting unit 20.

As shown in FIGS. 8 and 4 (A) and 4 (B), the light emitting unit 20 includes a light emitting element 21, a translucent cover 22, a first end cover 224, and a second end cover 225. , The wireless module 50 is provided. In addition to the light emitting element 21 and the translucent cover 22, the light emitting unit 20 includes, for example, a light emitting element substrate 23, a light emitting element support member 24, a substrate fixing member 25 (25a to 25n), a screw 26, and a spring receiving portion. 27 (27a and 27b), a power supply unit 28, and a reflection member 29 may be provided.
In FIGS. 4 (A) and 4 (B), reference numerals are given only to the screws 26 for fixing the substrate fixing member 25a, and reference numerals are given to the screws for fixing the substrate fixing member 25n from the substrate fixing member 25b. It is omitted.

Hereinafter, each part of the light emitting unit 20 will be described in detail.
The translucent cover 22 has a shape that covers the light emitting element 21 and enters the instrument body 10 when the light emitting unit 20 is attached to the instrument body 10. Here, the translucent cover 22 has an elongated shape, and has a "U" shape as shown in FIG. 9 in a cross section orthogonal to the longitudinal direction, except for the end portion in the longitudinal direction. Further, the translucent cover 22 has a function of diffusing the light radiated from the light emitting element 21.

As shown in FIGS. 4A and 4B, the translucent cover 22 covers the light emitting element 21. The second end cover 225 has a function of diffusing the light radiated from the light emitting element 21 like the translucent cover 22, and is attached so as to cover one end of the translucent cover 22. The first end cover 224 is attached so as to cover the other end of the translucent cover 22 with the wireless module 50 described later interposed between the first end cover 224 and the end 241 of the light emitting element support member 24.

Further, as shown in FIG. 9, the translucent cover 22 includes a light transmitting portion 221 that transmits light radiated from the light emitting element 21 and an entry portion 222 that enters the instrument main body. The entry portion 222 includes a first entry portion 222a and a second entry portion 222b.
That is, the translucent cover 22 has an intrusion portion 222 at an end portion of the mounting member 11 on the side close to the bottom plate portion 114 in a cross section orthogonal to the longitudinal direction. The amount of penetration of the penetration portion 222 is larger than the amount of deflection of the light emitting unit 20 when the light emitting unit 20 is attached to the instrument main body 10.

Since the entrance portion 222, which is a part of the translucent cover 22, enters the light emitting unit mounting recess 111 of the fixture body 10, even when the light emitting unit 20 is bent, the appearance of the lighting device is less likely to be deteriorated. This is because when the light emitting unit 20 is bent, only the entrance portion 222 of the translucent cover 22 that has entered the light emitting unit mounting recess 111 is exposed, and a gap is generated between the fixture main body 10 and the light emitting unit 20. This is because it disappears.

In the translucent cover 22, the end portion on the opening side forming the "U" shape having a cross-sectional shape is bent inward and downward. The lower part here is the side where the end opposite to the opening of "U" exists. In the cross section, the translucent cover 22 has an inwardly narrowing shape that inclines inward as it approaches the bent portion from the lower side, except for the bent portion.

Further, the translucent cover 22 has a projecting piece that projects inward at a portion away from the end on the opening side in a cross section orthogonal to the longitudinal direction. As shown in FIG. 14, the distance between the end portion and the protruding piece corresponds to the length of the folded portion of the light emitting element support member 24 described later. As a result, the portion (fitting portion) between the bent portion of the end portion of the translucent cover 22 and the protruding piece is fitted into the folded portion of the light emitting element support member 24, and the translucent cover 22 emits light. It is attached to the element support member 24. In this attached state, the folded portion of the light emitting element support member 24 and the inner surface of the translucent cover 22 are in contact with each other.
The entry portion 222 of the translucent cover 22 is included in the region where the folded portion of the light emitting element support member 24 and the inner surface of the translucent cover 22 are in contact with each other. As a result, the heat generated during the light emission of the light emitting element 21 is conducted to the mounting member 11 via the light emitting element substrate 23, the light emitting element support member 24, and the translucent cover 22.

The light emitting unit 20 is attached to the fixture main body 10 in a state where the inwardly narrowed intruding portion 222 is in contact with the outer wall surface of the light emitting unit mounting recess 111 of the fixture main body 10. At this time, it is sufficient that only a part of the entry portion 222 is in contact with the light emitting unit mounting recess 111, but the entire surface of the entry portion 222 may be in contact with the light emitting unit mounting recess 111.

As shown in FIGS. 4A and 4B, the light emitting element substrate 23 is a plate-shaped member elongated in one direction, and a plurality of light emitting elements 21 are mounted on one surface. Further, as shown in FIG. 10, the light emitting element substrate 23 may be configured by connecting a plurality of substrates (for example, the substrate 23a and the substrate 23b are connected).

As shown in FIGS. 10 and 11, a wiring for supplying electric power to the light emitting element 21 is connected to the light emitting element substrate 23. The wiring 28d connects the light emitting element substrate 23 and the power supply unit 28 through a through hole 24c provided in the substrate support region 24a of the light emitting element support member 24 described later. The electric power converted by the power supply circuit of the power supply unit 28 is supplied to the light emitting element 21 via the wiring 28d. The wiring 23c shown in FIGS. 10 and 11 is a wiring for electrically connecting the substrate 23a and the substrate 23b when the light emitting element substrate 23 is composed of a plurality of (two) substrates.

The light emitting element support member 24 supports the light emitting element substrate 23 on which the light emitting element 21 is mounted.
